  1. 6. Novel non-collagenous modulators of biomineralization in bone and dentin

    Författare :Eszter Somogyi-Ganss; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Calreticulin; nucleobindin; prothrombin; biomineralization; osteogenesis; dentinogenesis;

    Sammanfattning : The formation of mineralized tissues such as bones and teeth is governed on many levels by molecular, genetic, and cellular events to culminate in terminally differentiated cells that secrete a specialized organic matrix, which is later mineralized through the coordinated deposition of calcium phosphate crystals. The formation of this hard tissue phase is tightly regulated by components of the extracellular matrix (ECM), since deviations from this equilibrium result in prevalent, debilitating health problems such as arthritis, vascular calcification, periodontal disease and osteoporosis.

  3. 7. Bonding of resin to dentin. Interactions between materials, substrate and operators

    Författare :Thomas Jacobsen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Objectives: The general aim of this thesis was to identify and study factors that affect bonding between resin and dentin, including operator variability. Materials and methods: Bonding sites were generated in vivo and in vitro and compared using SEM. LÄS MER

  4. 8. Gene expression during hard tissue formation

    Författare :Catharina Ellerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone; dentin; mRNA; fibrillar collagens; osteonectin; fibronectin; development; rat;

    Sammanfattning : The purpose of this thesis was to study the formation of the extracellular matrix (ECM) of bone and dentin during development. Molecular techniques, such as in situ hybridization and RT-PCR, were used to investigate the occurrence of specific gene products in formative cells. LÄS MER

  5. 9. Developmental disturbances of cementum induced by 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP) : experimental studies on rats

    Författare :Idil Alatli Burt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :dental cementum; dentin; rat molar; bisphosphonate; mineralization; scanningelectron microscopy; immunohistochemistry; epithelial root sheath.Repro Print AB; Stockholm 1996;

    Sammanfattning : By studying the mechanism(s) behind experimentally induced developmental disturbances of a tissue, it may be possible to gain information about its normal development. Cementum seems to be the least understood of the dental tissues, and there are very few studies in which its development has been experimentally altered. LÄS MER

  7. 10. Endodontic treatment in young permanent teeth : prevalence, quality and potential risk factors

    Författare :Karin Ridell; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Nationell statistik över tandhälsan hos barn och ungdomar redovisar uteslutande uppgifter om karies som till exempel genomsnittligt antal karierade och fyllda tänder och antal karierade och fyllda tandytor i olika åldersgrupper. Det innebär att de saknas kunskaper om mer komplicerade och tidskrävande behandlingar som rotbehandling av unga permanenta tänder. LÄS MER
